Summary

We propose to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. (Honeywell) TPE331 turboprop and TSE331 turboshaft engines. This proposed AD was prompted by reports that combustion chamber case assemblies have cracked and ruptured. This proposed AD would require inspection of the affected combustion chamber case assembly, replacement of those assemblies found cracked, and removal of affected assemblies on certain TPE331 engines. We are proposing this AD to correct the unsafe condition on these products.

The agency’s own summary, as published.
